DOOR FOR GRAIN-CARS.

Specification. of Letters Patent.

Patented Dec. 18, 1906.

Application filed January 20, 1906. Serial No. 296,925.

To MU 'IFZHHIL it 72mg concern:

Be it known that we, THOMAS F. Mrron- ELL and HERMAN BAUMAN, citizens of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented a new and useful Door for Grain-Cars, of which the following is a speci fication.

Our invention relates to improvements in doors for grain-cars. The conditions under which such cars are used make it necessary. to provide an easily-movable door, which in the act of opening shall not be destroyed and when open shall be out of the way.

It is a fact familiar to those using graincars that large numbers of doors are destroyed in the efi'ort to open loaded cars and when open they project or he in such position as to be easily injured by accident. To obviate these difficulties and provide simple and efficient means of closing the opening in box-cars is one of the objects of our invention. Another object is to provide a car door which will effectively close the doorways of box-cars against the leakage of grain.

In the accompanying drawings, forming part of this specification, Figure 1 is a detail side view of a box-car, showing our improved door thereon. Fig. 2 is a detail sectional end view. Fig. 3 is a view looking at our improved door from inside of the car, and Fig. 4 is a detail sectional end view showing part of the door in superior position.

In thedrawings, A represents a detail portion of a grain-car, B its frame, and C one of its doorways.

Our improved door consists, in part, of a a pair of wings 3 and 4, which are hinged vertically at 5 and 6 upon said frame and adapted to swing out. The members of the hinges 5 and 6 are separable, so that the wings when open may be removed from the frame and hung, by means of hooks 7, upon loops 8 on the inner wall ofthe car. Chains 9 prevent the wings being carried away from the car. The inner edges 10 of the wings overlap the frame in the car, and their meeting edges 11 overlap each other to form tight joints and prevent the grain leaking out of the car. Metal plates 12, fastened on the vertical posts in the car, also serve the purpose of making tight oints between the door-frame and the wings and reduces wear of the parts.

Above the wings and across the doorway is a horizontal lockbar 13, made of wood or other suitable material, carrying metal protecting-strips 14, which are fastened thereto by any suitable means. The ends of the bar extend over the edges of the doorway when the bar is in normal position, and the bar is swung by means of arms 15, which are pivoted at 16 upon the frame, so as to turn up into superior position in the car when the door is opened. This bar carries an eyebolt 17.

A pair of lockbolts. 18 and 19 are used to lock the wings closed and are pivotally attached to a swinging lever 20, which is pivot ed at 21 upon the wing 3. The power end of this lever is locked by means of a dog 22 when the lock-bolts are set. Guides 23 hold the free ends of the lock-bolts on the wing 3 and guide them into the eyebolt 17 and notch 24 in the door-sill 25.

Swung by means of hinges 26 from the inner face of the bar is an extension 27,- which when the door is closed rests above the lookbar and laps over the sides of the frame of the doorway in the car, as shown in Fig. 3. This extension is fastened to the frame of the doorway when closed by means of hooks 28.-

i/Vhen the door is opened, the lock-bolts 18 and 19 are released by swinging the dog 22 up and raising the power end of the lever 20. The hooks 28 are unfastened and the extension and lock-bar 13 are swung up into the position shown in Fig. 4. These parts may be supported in superior position by means of a hook 29, which may be fastened to the roof in the car and adapted to engage a notch 30 in the extension. The wings of the door may be swung out upon their hinges and removed when desired.

Having described our invention, what we claim as new, and desire to protect by Letters Patent, is

1. A sectional swinging car-door, the sec tions of which are adapted to open horizontally and vertically in the dooropening, consisting of two wings hinged to the sides of said door-opening, a horizontal lock-bar inside the car and across said opening, rods pivoted to the sides of said opening carrying said bar and adapted to swing upward, an extension carried by said bar above said wings and adapted to rest across said open ing in the car, and means for locking the sections of said door closed.

2. The combination, with a car having a doorway, of a pair of wings hinged at the sides of said doorway and adapted to swing outward, a horizontal bar across said opening llO in the car and above said wings, a lock carried by one of said wings and adapted to engage said bar and the sill of said doorway to hold the members of said door closed, hinges at the sides of said doorway by which said bar is adapted to swing upward in the car,

- an extension above, and hinged to, said bar,

and means for fastening said extension across said opening.

3. The combination, with a car having a doorway, of wings adapted to swing outward, separable hinges by which said-wings arehinged vertically to the sides of said doorway, a lock-bar-across said opening in the car and above said wings, means by which said bar is adapted to swing upward in the car, and a look by which said wings are held closed and in-engagementwith said bar and the sill of said doorway.

- 4. The combination, with a car having a doorway, of wings across said doorway and adapted to swing outward, hinges by which said wings are carried vertically upon the sides of said doorway, a lock-bar across said doorway in the car, a look by which said wings are held closed and in engagement with said bar, means supported at the sides of said doorway by which said bar is adapted to swing upward in the car, and an extension above said bar and across said doorway.

5. The combination, with a carhaving a doorway, of wings across said doorway adapted to swing outward in a horizontal plane,hinges by which said wings are carried on the sides of said doorway, a lock-bar across said doorway and above said wings, a lock adapted to hold said wings closed andin engagement with said bar and the sill of said doorway, swinging arms pivoted to the sides of said doorway, carrying said bar. and adapted to swing upward in the car, an extension hinged to said bar and extending across said doorway to assist in closing the same, and means for holding said extension closed.

6. The combination, with a car having a doorway, of wings 3 and 4-having their inner edges lapping over the sides of-said doorway in the car and their meeting edges overlappingeach other, separable hinges 5 and 6 by which said wings are carried-upon the sidesof said doorway and adapted to swing outward in a horizontal plane, a lock-bar 13 across said doorway in the car and above said wings, lock-bolts 18 and 19- adapted to engage said bar and the sill of said doorway, a lever. 20 pivoted upon one of saidwings and-connected withsaid lock-bolts, a dog 22 adapted to lock said leverand hold said lock-bolts-in closed position, arms 15 pivoted upon the sides of said doorway and carrying said lockbar, an extension 27 across said doorway in the car and above said bar, hinges 26 by which said extension is adapted to swing upon said bar, and. means for holding said extension across said doorway.

Intestimony whereof we have signed our namesto this specification in the presence of two subscribing witnesses.
